DISCUSSION
(This Evening Through Saturday) Issued at 118 PM MST Sat Dec 13 2025
Current Water Vapor and upper air models show ridge over the west coast, with northwest flow over the forecast area. Surface analysis shows high pressure settling over the Dakotas, with a low over western WY. Temperatures currently sit in the single digits for most of the region, while the Black Hill areas range in the teens to almost 30. Winds are generally light and variable this afternoon.
Snow has generally tapered off across the CWA aside from some lingering light flurries over the Black Hills that will not last much longer. Cold temperatures will remain through tonight, with some areas getting to right around 0 degrees. Upper ridge builds over the Rockies Sunday and low level southwesterly WAA sets up as well, resulting in a warming trend to start the week, with highs climbing into the 40s to low 50s for most of the forecast area tomorrow. Expect these warmer and generally dry conditions to stay for the first half of next week, with little change to the overall pattern. Mid-week the upper flow becomes more zonal, and models hint at a wave moving through southwest Canada and eventually into the northern plains by Wednesday/Thursday. This will bring our next chance for precipitation and a brief drop in temperatures. Lower confidence in timing and precipitation amounts this far out, but will be monitoring as we move through next week. Long range models keep a more active zonal flow later next week, with the potential for more chances at light precipitation over the weekend.
